Understanding kidney cancer....!!!
Kidney cancer is a malignant tumour developed from the kidney cells. Malignant kidney tumours account for 2-5% of malignant cancers in adults. Men are affected twice as often as women. Cancers constitute 85% of kidney tumours.
The good news is that most of kidney cancers are found before they spread (metastasize) to distant organs. And cancers caught early are easier to treat successfully. However, these tumors can grow to be quite large before they are detected.

The kidneys are two bean-shaped organs, each about the size of a fist. They lie in your lower abdomen on each side of your spine. Their main job is to clean your blood, removing waste products and making urine.
Kidney cancer includes renal cell carcinoma that forms in the lining of tiny tubes inside your kidneys.Another type of cancer, renal pelvis carcinoma, affects the renal pelvis (its the center of the kidney where urine collects).It also includes Wilms tumor, which is a type of kidney cancer that usually develops in children under the age of 5. It is different from adult kidney cancer and requires different treatment. |

SEER Incidence...!!!
From 2005-2009, the median age at diagnosis for cancer of the kidney and renal pelvis was 64 years of age. Approximately 1.3% were diagnosed under age 20; 1.7% between 20 and 34; 6.0% between 35 and 44; 16.5% between 45 and 54; 25.6% between 55 and 64; 24.7% between 65 and 74; 18.4% between 75 and 84; and 5.8% 85+ years of age.
The age-adjusted incidence rate was 15.1 per 100,000 men and women per year. These rates are based on cases diagnosed in 2005-2009 from 18 SEER geographic areas.

Survival & Stage...!!!
Survival can be calculated by different methods for different purposes. The survival statistics presented here are based on relative survival, which measures the survival of the cancer patients in comparison to the general population to estimate the effect of cancer. The overall 5-year relative survival for 2002-2008 from 18 SEER geographic areas was 70.6%. Five-year relative survival by race and sex was: 70.8% for white men; 71.0% for white women; 68.1% for black men; 68.1% for black women.
